To r/.ZZ whom. it may concern:

Beit known that we, JACOB OYTRoN, Gus- Tav GYTRoN, and .IULIUS CYTRON,citizens of the United States, residing at St. Louis, in the State ofMissouri, have invented certain new and useful Improvements inMechanically- Operated Cradles; and we do hereb)7 declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

Our invention relates to improvements in niechanically-operated cradles;and it consists in the novel combination and arrange ment. of parts, aswill be hereinafter more par-Y ticularly described and claimed.

In the drawings, Figure 1 is a top plan View of our complete invention,and Fig. 2 is a side elevation thereof.

The object of our invention is to construct a simple and practicalinechanically-operated device or movement which maybe wound up and whenproperly attached to a cradle of the well-known construction the latterwill be operated or rocked a suitable length of time without furtherattention.

Referring to the drawings, 1 represents a cradle of the well-knownconstruction and consisting of a stationary supporting-base 2, aswinging or movable portion 3, which is adapted to hold and carry theordinary mattresses, an d et hangers, the upper ends of which aremovably attached to the stationary base 1 and having their lower endsmovahly attached to the lower portion of the upper frame 3, whereby thelatter is adapted to swing upon said stationary base when operated ineither direction.

Secured to the opposite sides of the swinging frame 3 and located on theinside thereof is a transverse beam 5, to one of the Vertical sides ofwhich is secured a rack-bar 6,

with which the operating mechanism is adapte ed to cooperate.

Located on the inside of the supportingbase 2 and secured to theopposite ends thereof is a bed 7, to which is attached a bearing S,carrying a shaft 9,v to one of its free ends of which is secured aworm-pinion 10, which meshes with a worm-gear 11, which is Vliked to avertical shaft l2, which is carried and is movably fixed to thesupporting-bed 7. Also fixed to the shaft 12 and located above theworm-gear 11 is a disk or plate 13, having three sets of teeth 14cformed on its edge which cooperate with the rack-bar 6, carried by thetransverse beam 5, a suitable space being left between the teeth 14,which freely passes the said rack-bar when the said disk is turned, theteeth only cooperating with the rack-bar intermittingly. Fixed to theoppovsite end of the shaft 9 is a pinion 15, with which meshesagear-wheel1(3,loosely mounted upon a shaft 17, carried by the bracket18, and secured to the said shaft 17 adjacent to the gear-wheel 1G is aratchet-disk 19, which cooperates with a pawl 20, carried by the saidgear-wheel.

Secured to the transverse beam 5 is one end of a fiat clock-spring 21,the opposite end of which is attached to the shaft 17, which operates toturn the said shaft in one direction when wound up, and thereby operatethe remaining parts heretofore described.

The outer end of the shaft 17 is loosely received by a bracket 22, andsecured to the said shaft adjacent to said bracket is a ratchet-disk 23,with which cooperates a pawl 24, movably carried by the gear 25, locatedadjacent to said ratchetdisk and loosely mounted upon the said shaft.Cooperating with the gear-wheel 25 is a vertically-operated rack-bar 26,which is guided and held in its proper position in respect to thegearwheel 25 by guides 27, the upper end of said rack-bar having afoot-plate 28, which is adapted to be pressed by the foot or hand of theoperator for winding up the spring 21, the said rack-bar being raisedautomatically when released by a coil-spring which encircles the lowerend of said rack-bar and is interposed between the collar 29, formingapart of said rack-bar, and the bracket 30, through which the latterpasses.

From the foregoing description it will be seen that when the rack-bar 26is depressed the gear-wheel 25 will be turned in one direction, causingthe shaft 17 to be likewise turned by the employment of the ratchetdisk23, fixed to said shaft, and the pawl 2st, carried by said gear-wheel,in Which operation the ratchet-disk 29 will also be turned,

IOO

- 10, fixed to the same, which in turn operates i.

causing the paWl 20, carried by the gearwheel 16, to ride over theratchet-disk 19, and thereby Wind up the spring 2l, as is'com mon in allclock mechanism, and when the rack-bar 26 is released the spring locatedat the lower end of the same will force lthe said bar upwardly to itsnormal position, the pawl I 24, carried by the gear-Wheel' 25, ridingrover the teeth of the ratchet-disk 23. After the spring 21 has beenWound up, as described, the gear-Wheel 16 will be setin motion, turningthe pinion l5, shaft 9, and worm-pinion or turns the Worm-gear 1l, shaftl2, and toothed plate 13, the latter meshingV with the rack-bar 6 ot'the transverse beam 5, carried by the swinging frame 3, forming a partof the cradle. Thus it will be seen that the swinging frame 3 ismechanically operated only in one direction andthe momentum given thesame swinging the said frame in the opposite direction after the teeth14 of the plate 13 have passed the rack-bar G.

We do not limit ourselves to the exact construction of the mechanicaldevice herein employed, as the same may be varied or changed Withoutdeparting from the nature of our invention, nor do welimit ourselves toits specific application herein shown andde- 1 scribed, as any otherfurniture of a rocking 3o natur@ may he 4likewise operated. Furthermore,any suitable power may be employed for operating the various partscomprisingn our invention, and, further, any suitable means may, be usedfor placing the motor in lits proper condition for use.

Having fully described our invention, what We Claim iS- A cradle,comprisinga stationary and movable part, a transverse beam forming apart of the latter, a rack-har secured to said beam,
